APPARATUS FOR TRIMMING PHOTOGRAPHIC PRlNTS.

SPECIFICATION forming part of Letters Patent No. 476,481, dated June '7,1892.

Application filed February 23, 1892. Serial No. 422,362. (No model.)

Toall whom it may concern:

Be it known that I, HARRY H. NEwcoMB, of Boston, in the county ofSuffolk and State of Massachusetts, have invented certain new and usefulImprovements in Apparatus for Trimming Photographic Prints, of which thefollowing is a specification.

This invention has forits object to provide a simple and convenientdevice whereby photographic prints may be trimmed in rectangnlar formand to any desired size; and it consists in the improvements which Iwill now proceed to describe.

Of the accompanying drawings, forming part of this specification, Figure1 represents a perspective view of my improved trimming apparatus. Fig.2 represents a top plan View of the same. Fig. 3 represents a section online 3 3, Fig.

The same letters of reference indicate the same parts in all thefigures.

In carrying out my invention I provide a supporting base or bed a ofrectangular form, which is provided with a series of guiding lines ormarks I) b h, extending parallel with one of its sides, and a similarseries of marks b b 1), extending parallel with another of its sides,the marks I) and Z) forming right angles, as shown in Fig. 2. I preferto form the marks I) 1) upon a surface which is covered by a transparentplate 0, of glass, the marks being formed on thematerialof which thesupporting-base is composed, said material being preferably of wood. Theglass plate a protects the base and the marks thereon and acts as acutting-bed to adapt it to co-operate with a hardened steel rotaryknife, such as is commonly used in trimming photographs. The bed a isprovided upon two of its sides with raised tlanges a a said flangesforming a right angle.

(Z represents a rectangular plate, preferably of glass, of smaller sizethan the base a, and so proportioned that when two of its edges bearagainst the flanges a a its other two edges will co-operate with thelines I) b in forming a rectangle of given dimension which dimensionsare preferably marked upon the base a in suitable proximity to thelines. In other words, the edges 2 3 of the plate (Z co-operate with oneset of lines I) b in forming a rectangle of the size for which saidlines were intended, one side of said rectangle being, for example,three and one-fourth inches long and the other one and three-fourthsinches long. The next set of lines I) 1) cooperate with said edges informing a rectangle, which may be five inches long in one direction andfourinches long in another, and so on, the edges of the plate clco-operating with as many sets of lines I) Z) as may be formed upon thebase.

The operation is as follows: A print 6 to be trimmed is placed upon aglass plate 0, and the plate at is placed upon it and held down withsufficient firmness to retain the print in place while the operatortrims its projecting edges by means of a suitable tool guided by theedges 2 3 of the plate d. The operator then turns the print around, sothat its trimmed edges will coincide with the lines I) b of the desiredsize, and then trims the other two edges in the same manner, the resultbeing that the print is cut in an exactly rectangular form and of theexact size of the rectangle described by the edges 2 3 of the plate (Zand the lines I) b on the bed.

It will be seen that this improved device enables the operator toquickly and accurately trim photographic prints without liability ofcutting the prints out of true by their slipping while being cut.

The device is particularly intended for the use of amateurphotographers, although it may obviously be used for trimming paper orlike material for any other purpose or purposes.

I claim- 1. A paper-trimming device comprising in its construction a bedprovided at two of its edges with raised stops or flanges a a and on itsface with lines I) b, all relatively arranged, as shown, and a plate orguide (Z, formed to hear at two of its edges against the stops a a andto bear on the bed, two of the edges of said plate constituting guidesfor a trimming-tool, as set forth.

2. A paper-trimming device comprising in its construction, first, a bedhaving raised stops a a at two of its edges, lines I) b on its face, anda transparent plate 0, covering said lines and constituting acutting-bed, and, sec- IOO ondl'y, atransparent plate or guide (Z,formed two subscribing Witnesses, this 18th day of to bear at two of itsedges against the stops February, A. D. 1892. a a and to bear onthebed,two of the edges of said plate constituting guides for a trim- 5ming-tool, as set forth. \Vitnesses:

In testimony whereof I have signed my C. F. BROWN, name to thisspecification, in the presence of A. D. HARRISON.
